Black Widow changed multiple writers over the course of production, and only in a very early draft of the script did Tony Stark appear.
In an interview with ComicBook.com’s Phase Zero podcast, Black Widow writer Eric Pearson revealed that an early version of the script did include a Tony Stark appearance.
The film also sets up Yelena as the future Black Widow.
After a long wait, Marvel’s long overdue Black Widow is finally out in theaters and streaming on Disney+.
